>I even think that China could make the entire west civilization collapse just by stopping their exportation.

Then the West retaliates by stopping their export to China of even more basic things like food. I'm guessing China needs food imports much more than the West needs cheap plastic wares, knock off products, and other less critical than food things.

For consumer goods, sure. But much of that is not what makes up the entire west civilization, imho

A lot of people in the west couldn't potentially afford a single modern computer or a smartphone without any piece from China.

At least it would push us to take reusing more seriously. Brutal decoupling from China could be really, probably extremely hard, but in a lot of aspects, intellectually interesting to watch.

How Europe will react to adapt the current crisis regarding fossils will also be really interesting. I'm just hoping that it will accelerate the de-carbonation of our energy sources. But it's just that, hopes.
